fdt: boot_get_fdt: android: use ENV 'fdtaddr' as fallback

Our platform doesn't store the DTB into the Android image second area,
but rather copies the DTB to RAM from a dedicated dtb.img partition [0],
prior to booting the Android image by calling bootm.

Similar to [1], we find it useful to just call 'bootm' and have the
right DTB being passed to OS (assuming its address has been previously
stored in 'fdtaddr' by calling `fdt addr <dtb-addr>`).

Booting Android with DTB from 'fdtaddr' will only occur if:
 - No DTB is embedded in the second area of Android image
 - 'fdtaddr' points to a valid DTB in RAM

5 years agofdt: boot_get_fdt: really boot w/o FDT when "goto no_fdt"
Eugeniu Rosca [Mon, 1 Apr 2019 10:45:34 +0000 (12:45 +0200)]
fdt: boot_get_fdt: really boot w/o FDT when "goto no_fdt"

The 'no_fdt' goto label was introduced by v2015.01 commit [0] and it
had two review stages [1-2]. The *documented* purpose behind commit [0]
is (excerpt from commit description):

> allows both FDT and non-FDT kernels to boot by making the
> third parameter to the bootm/bootz optional

While [1] and [2] share the same goal, they have very different
implementations:
 - [1] was based on a very simple 'argc' check at function error out
   with returning success to the caller if the third parameter was NOT
   passed to bootm/bootz command. This approach had the downside of
   returning success to the caller even in case of legitimate internal
   errors, which should halt booting.
 - [2] added the "no_fdt" label and several "goto no_fdt" statements.
   This allowed to report the legitimate internal errors to the caller.

IOW the major difference between [1] and [2] is:
 - [1] boot w/o FDT if FDT address is not passed to boot{m,z,*}
 - [2] give *freedom* to the developer to boot w/o FDT from any
   (more or less) arbitrary point in the function flow (and here
   comes the peculiar aspect, which looks to be a leftover from [1])
   with the precondition that the 3rd argument (FDT address) is NOT
   provided to boot{m,z,*}. In practice, this means that only a subset
   of "goto no_fdt" end up booting w/o FDT while the other subset is
   returning an error to the caller.

This patch removes the peculiar behavior described above, such that
"goto no_fdt" performs really what it tells to the developer.

The motivation of this patch is to decrease the unneeded complexity
and increase the readability of boot_get_fdt().

fdt: boot_get_fdt: remove redundant zeroing out

Paranoid programming [1] lies at the foundation of proper software
development, but the repetitive zeroing-out of output arguments in the
context of the same function rather clutters the code and inhibits
further refactoring/optimization than is doing any good.

In boot_get_fdt(), we already perform zero/NULL-initialization of
*of_flat_tree and *of_size at the beginning of the function, so doing
the same at function error-out is redundant/superfluous.

Moreover, keeping the code unchanged might encourage the developers to
update *of_flat_tree and *of_size during some interim computations,
which is against the current design of boot_get_fdt(). Currently,
writing useful data into these arguments happens just before
successfully returning from boot_get_fdt() and it should better stay so.

usb: dwc2: fix gadget disconnect

This fixes a disconnect issue detected with fastboot command, when using
dwc2 driver.
- On u-boot side:
uboot>$ fastboot 0
- On USB host PC side, few seconds after
PC>$ fastboot reboot # Get stuck, uboot target never reboots

By enabling DEBUG_ISR logs, the bus suspend interrupt is seen before the
PC command has been issued. When the USB bus suspend occurs, there's a HACK
that disables the fastboot (composite driver). Here is the call stack
upon USB bus suspend:
- dwc2_handle_usb_suspend_intr()
  - dev->driver->disconnect()
    - composite_disconnect()
      - reset_config()
        - f->disable()
          - fastboot_disable()
            - usb_ep_disable(f_fb->out_ep);
            - usb_ep_disable(f_fb->in_ep);
            .. other disable calls.

When the resume interrupt happens, everything has been disabled, then
nothing happens. fastboot command gets stuck on HOST side.

Remove original HACK, that disconnects the composite driver upon
USB bus suspend. Implement disconnect detection instead:
- check GINTSTS OTG interrupt
- read GOTGINT register
- check GOTGINT, SesEndDet bit (e.g. session end)
This is inspired by what is implemented currently in Linux dwc2 driver.

sunxi: update SATA driver to always use DM_SCSI

It seems like the Allwinner SATA driver is already quite capable of
using the driver model, so we can force this on all boards and can
remove support for a non-DM_SCSI build.
This removes the warning about boards with SATA ports not being
DM_SCSI compliant.

It also takes the opportunity to move the driver out of the board/sunxi
directory to join its siblings in drivers/ata, and to make it a proper
Kconfig citizen.

The board defconfigs stay untouched.
